Pollen Count & Forecast for Wrocław

Wrocław’s spring allergy season (March-May) is dominated by Birch and Alder pollen; Birch (Betula) is common in Park Szczytnicki and Park Południowy; Alder (Alnus) is widespread along the Odra riverbanks. Summer (May-July) has high Grass (Poaceae) pollen levels; these originate from meadows in Park Grabiszyński and the Bystrzyca river valley. Mugwort (Artemisia) is frequent in late summer across open urban spaces.

The flat Silesian Lowlands and multiple river branches trap pollen; high humidity in the Odra valley increases local concentrations. Autumn has elevated Mould (Alternaria, Cladosporium) spore counts; these come from decaying leaf litter in the ZOO gardens and the City Moat areas.
